What is solar welding?

Simply put, solar welding is using solar to run a welding machine. A welder can also run off a generator or the grid, but solar is exceptional for being cost-effective and environment-safe. As solar becomes more integrated into critical processes like welding, we have hope that it’ll eventually power most of our everyday activities.

How do you wire a solar panel?

1. Add tab wires as needed to the end of the strings. 2. Lay the strings next to each other with a small space in between them. I would recommend doing this on the glass you will be using for the solar panel, or on something that these cells can be kept on until they are ready to be put into a panel.

How much wire do you use for a 1" solar cell?

When using 1" solar cells i use tab wires that are 1 3/4" long. When you wrap the wire around the 3/8" pipe it comes out close enough to what I need (1/2"pipe o.d. x 3.14= 1.57"+ any slack deviations). I milled a slot down one side so one of the scissor blades could fit through it.

How do you jig solar cells while soldering?

The first jig is to hold the solar cells while soldering. I made this from a piece of scrap wood and some small nails. I laid out a few of the solar cells on the board and marked places to put the nails. Make sure you put the nails in places that when you are soldering that they do not get in the way of your solder iron.

How to solder a solar cell?

Moving from top to bottom, use your soldering iron and start soldering the tab wire down. Don't let your iron set in one place to long, you will burn the solar cell. You will need to move your holding tool around as you move the iron down, don't let the tab wire move. Hold the tab wire down until the solder cools. 5.

What size jig do you use for solar cells?

The board i am using is large enough to put 4 solar cells in a row on it. The second jig is used to make the tabbing wires for the solar cells. It is a piece of 3/8" x 6" black pipe. The outside diameter of a 3/8 pipe is a little more than 1/2". When using 1" solar cells i use tab wires that are 1 3/4" long.
